With the nationally watched buttock-swatting trial of two McMinnville middle school boys set to begin, a Yamhill County judge this morning dismissed the sexual-harassment charges against the 13-year-olds. But before he dismissed the case, Judge John L. Collins required the boys to issue a public apology in court. Cory Mashburn and Ryan Cornelison stood, turned and, speaking with voices just above a whisper, said they were sorry to their accusers. Reporter Joseph Rose of The Oregonian was in the courtroom and filed these video highlights.
